Arsenic Mitigation in Rural Bangladesh: A Policy-Mix for Supplying

Naturally-occurring arsenic in Bangladesh's groundwater has been identified as one of the world's great humanitarian disasters, with millions people at risk of cancers and other diseases from Arsenic contaminated groundwater is used extensively in Bangladesh to irrigate the staple food of the region, paddy rice (Oryza sativa L.).To determine if this irrigation has led to a buildup of arsenic levels in paddy fields, and the consequences for arsenic exposure through rice ingestion, a survey of arsenic levels in paddy soils and rice grain was undertaken. Bangladesh has high well water arsenic exposure. Chronic arsenic ingestion may result in diseases that manifest as dyspnoea, although information is sparse. Baseline values were obtained from an arsenic study. Trained physicians ascertained data on dyspnoea among 11,746 subjects. It has recently been estimated that these wells have exposed about half of the population in Bangladesh to arsenic concentrations above 10 μg/L (the WHO guideline value 18), with wide variations in exposure. 19 Although a large part of the Bangladeshi population has been exposed for long-enough times to cause arsenic-related deaths, 20 no study has yet shown such mortality effects.
